--- Quote from: mickwinf on July 26, 2023, 11:27:31 PM ---So continuing with the electrics I have a new battery fitted and starting to connect things up. Not fully assembling for now but checking everything works. I have starter motor, front lights and idiot lights all OK. I tried turning engine over to see if oil pressure light went off but not yet. I recall some discussion about priming the oil pump? Not ready for starting yet as cards need rebuild but getting there slowly. Oh has anyone got a spare positive battery lead for sale as mine is wrong.

you should not need to prime a 500 or 550 pump Mick.  ;)

Bryanj:
I agree with Trigger on that but did have one that sat for many years and just removed pressure switch and filled using squirty oil can, did bring pressure up quicker

Sesman:
It’s possible that it was me who asked about oil pump priming. As I recall, I’d read something about using Vaseline, until I was reminded this was associated with the 750 and dry sump systems (thanks trigger). As was stated at the time, “no need to prime wet sump systems” and indeed that proved to be the case.

Johnny4428:
I appeared to have a problem getting oil pressure up on my 550 on initial fire up after rebuild, and first oil change. Since changed oil pressure switch and carried out oil pressure checks, so quite sure the switch was faulty.

mickwinf:
It is a new genuine oil pressure switch, and I have taken the tappet cover to see if any oil getting up there but none yet. Oil pump has new seals from nurse Julie.
